DATE_FORMAT not working

Hi I can’t get DATE_FORMAT, DATE_INPUT_FORMATS, or any related settings to work. Django doesn’t appear to recognise my settings either when displaying dates in the template or using form fields. This appears to be a new issue as I recently migrated to Django 5 and didn’t encounter it before.

Relevant settings:

DATE_FORMAT = "d.m.Y"
DATETIME_FORMAT = "d.m.Y P"
SHORT_DATETIME_FORMAT = DATETIME_FORMAT

DATE_INPUT_FORMATS = [
    "%d.%m.%Y",
    "%d.%m.%y",
    "%d/%m/%Y",
    "%d-%m-%Y",
    "%d/%m/%y",
    "%d-%m-%y",
]

DATETIME_INPUT_FORMATS = [
    "%d.%m.%Y %H:%M:%S",
    "%d.%m.%y %H:%M:%S",
]

USE_I18N = False

USE_L10N = False

USE_TZ = False

This problem also appears in the Django shell. e.g.:

>>> from django.utils.timezone import now
>>> from django.template import Context, Template
>>> Template('{{ d|date:"DATE_FORMAT" }}').render(Context({'d':now}))
'May 2, 2024'
>>> from django.conf import settings
>>> settings.DATE_FORMAT
'd.m.Y'

Does anybody know what is going wrong here?
